-
-  The `conmon` version that Podman uses and Ubuntu Jammy ships, has a bug
-  that gets triggered by Dangerzone
-  (more details in https://github.com/freedomofpress/dangerzone/issues/685).
-  If you want to run Dangerzone from source, you are advised to install a
-  patched `conmon` version. A simple way to do so is to enable our
-  apt-tools-prod repo, just for the `conmon` package:
-
-  ```bash
-  sudo cp ./dev_scripts/apt-tools-prod.sources /etc/apt/sources.list.d/
-  sudo cp ./dev_scripts/apt-tools-prod.pref /etc/apt/preferences.d/
-  ```
-

-## Qubes OS
-
-
-> :warning: Native Qubes support is in beta stage, so the instructions below
-> require switching between qubes, and are subject to change.
->
-> If you want to build Dangerzone on Qubes and use containers instead of disposable
-> qubes, please follow the instructions of Fedora / Debian instead.
-
-
-### Initial Setup
-
-The following steps must be completed once. Make sure you run them in the
-specified qubes.
-
-Overview of the qubes you'll create:
-
-| qube         |   type   | purpose |
-|--------------|----------|---------|
-| dz           | app qube | Dangerzone development |
-| dz-dvm       | app qube | offline disposable template for performing conversions |
-| fedora-41-dz | template | template for the other two qubes |
-
-#### In `dom0`:
-
-The following instructions require typing commands in a terminal in dom0.
-
-1. Create a new Fedora **template** (`fedora-41-dz`) for Dangerzone development:
-
-   ```
-   qvm-clone fedora-41 fedora-41-dz
-   ```
-
-   > :bulb: Alternatively, you can use your base Fedora 40 template in the
-   > following instructions. In that case, skip this step and replace
-   > `fedora-41-dz` with `fedora-41` in the steps below.
-
-2. Create an offline disposable template (app qube) called `dz-dvm`, based on the `fedora-41-dz`
-   template. This will be the qube where the documents will be sanitized:
-
-   ```
-   qvm-create --class AppVM --label red --template fedora-41-dz \
-       --prop netvm="" --prop template_for_dispvms=True \
-       --prop default_dispvm='' dz-dvm
-   ```
-
-3. Create an **app** qube (`dz`) that will be used for Dangerzone development
-   and initiating the sanitization process:
-
-   ```
-   qvm-create --class AppVM --label red --template fedora-41-dz dz
-   qvm-volume resize dz:private $(numfmt --from=auto 20Gi)
-   ```
-
-   > :bulb: Alternatively, you can use a different app qube for Dangerzone
-   > development. In that case, replace `dz` with the qube of your choice in the
-   > steps below.
-   >
-   > In the commands above, we also resize the private volume of the `dz` qube
-   > to 20GiB, since you may need some extra storage space when developing on
-   > Dangerzone (e.g., for container images, Tesseract data, and Python
-   > virtualenvs).
-
-4. Add an RPC policy (`/etc/qubes/policy.d/50-dangerzone.policy`) that will
-   allow launching a disposable qube (`dz-dvm`) when Dangerzone converts a
-   document, with the following contents:
-
-   ```
-   dz.Convert         *       @anyvm       @dispvm:dz-dvm  allow
-   dz.ConvertDev      *       @anyvm       @dispvm:dz-dvm  allow
-   ```
-
-#### In the `dz` app qube
-
-In the following steps you'll setup the development environment and
-install a dangerzone build. This will make the development faster since it
-loads the server code dynamically each time it's run, instead of having
-to build and install a server package each time the developer wants to
-test it.
-
-1. Clone the Dangerzone project:
-
-   ```
-   git clone https://github.com/freedomofpress/dangerzone
-   cd dangerzone
-   ```
-
-2. Follow the Fedora instructions for setting up the development environment.
-
-3. Build a dangerzone `.rpm` for qubes with the command
-
-   ```sh
-   ./install/linux/build-rpm.py --qubes
-   ```
-
-4. Copy the produced `.rpm` file into `fedora-41-dz`
-   ```sh
-   qvm-copy dist/*.x86_64.rpm
-   ```
-
-#### In the `fedora-41-dz` template
-
-1. Install the `.rpm` package you just copied
-
-   ```sh
-   sudo dnf install ~/QubesIncoming/dz/*.rpm
-   ```
-
-2. Shutdown the `fedora-41-dz` template
-
-### Developing Dangerzone
-
-From here on, developing Dangerzone is similar to Fedora. The only differences
-are that you need to set the environment variable `QUBES_CONVERSION=1` when
-you wish to test the Qubes conversion, run the following commands on the `dz` development qube:
-
-```sh
-
-# run the CLI
-QUBES_CONVERSION=1 poetry run ./dev_scripts/dangerzone-cli --help
-
-# run the GUI
-QUBES_CONVERSION=1 poetry run ./dev_scripts/dangerzone
-```
-
-And when creating a `.rpm` you'll need to enable the `--qubes` flag.
-
-> [!NOTE]
-> Prefer running the following command in a Fedora development environment,
-> created by `./dev_script/env.py`.
-
-```sh
-./install/linux/build-rpm.py --qubes
-```
-
-For changes in the server side components, you can simply edit them locally,
-and they will be mirrored to the disposable qube through the `dz.ConvertDev`
-RPC call.
-
-The only reason to build a new Qubes RPM and install it in the `fedora-41-dz`
-template for development is if:
-1. The project requires new server-side components.
-2. The code for `qubes/dz.ConvertDev` needs to be updated.

-
-### Changed
-
-- The second phase of the conversion (pixels to PDF) now happens on the host. Instead of first grabbing all of the pixel data from the first container, storing them on disk, and then reconstructing the PDF on a second container, Dangerzone now immediately reconstructs the PDF **on the host**, while the doc to pixels conversion is still running on the first container. The sanitation is no less safe, since the boundaries between the sandbox and the host are still respected ([#625](https://github.com/freedomofpress/dangerzone/issues/625))
-- PyMuPDF is now vendorized for Debian packages. This is done because the PyMuPDF package from the Debian repos lacks OCR support ([#940](https://github.com/freedomofpress/dangerzone/pull/940))
-- Always use our own seccomp policy as a default ([#908](https://github.com/freedomofpress/dangerzone/issues/908))
-- Debian packages are now amd64 only, which removes some warnings in Linux distros with 32-bit repos enabled ([#394](https://github.com/freedomofpress/dangerzone/issues/394))

-#                       REUSING CONTAINER IMAGES:
-#                          Anatomy of a hack
-#                       ========================
-#
-# The rest of the Dockerfile aims to do one thing: allow the final container
-# image to actually contain two container images; one for the outer container
-# (spawned by Podman/Docker Desktop), and one for the inner container (spawned
-# by gVisor).
-#
-# This has already been done in the past, and we explain why and how in the
-# design document for gVisor integration (should be in
-# `docs/developer/gvisor.md`). In this iteration, we want to also
-# achieve the following:
-#
-# 1. Have a small final image, by sharing some system paths between the inner
-#    and outer container image using symlinks.
-# 2. Allow our security scanning tool to see the contents of the inner
-#    container image.
-# 3. Make the outer container image operational, in the sense that you can use
-#    `apt` commands and perform a conversion with Dangerzone, outside the
-#    gVisor sandbox. This is helpful for debugging purposes.
-#
-# Below we'll explain how our design choices are informed by the above
-# sub-goals.
-#
-# First, to achieve a small container image, we basically need to copy `/etc`,
-# `/usr` and `/opt` from the original Dangerzone image to the **inner**
-# container image (under `/home/dangerzone/dangerzone-image/rootfs/`)
-#
-# That's all we need. The rest of the files play no role, and we can actually
-# mask them in gVisor's OCI config.
-#
-# Second, in order to let our security scanner find the installed packages,
-# we need to copy the following dirs to the root of the **outer** container
-# image:
-# * `/etc`, so that the security scanner can detect the image type and its
-#   sources
-# * `/var`, so that the security scanner can have access to the APT database.
-#
-# IMPORTANT: We don't symlink the `/etc` of the **outer** container image to
-# the **inner** one, in order to avoid leaking files like
-# `/etc/{hostname,hosts,resolv.conf}` that Podman/Docker mounts when running
-# the **outer** container image.
-#
-# Third, in order to have an operational Debian image, we are _mostly_ covered
-# by the dirs we have copied. There's a _rare_ case where during debugging, we
-# may want to install a system package that has components in `/etc` and
-# `/var`, which will not be available in the **inner** container image. In that
-# case, the developer can do the necessary symlinks in the live container.
-#
-#                           FILESYSTEM HIERARCHY
-#                           ====================
-#
-# The above plan leads to the following filesystem hierarchy:
-#
-# Outer container image:
-#
-#     # ls -l /
-#     lrwxrwxrwx   1 root   root       7 Jan 27 10:46 bin -> usr/bin
-#     -rwxr-xr-x   1 root   root    7764 Jan 24 08:14 entrypoint.py
-#     drwxr-xr-x   1 root   root    4096 Jan 27 10:47 etc
-#     drwxr-xr-x   1 root   root    4096 Jan 27 10:46 home
-#     lrwxrwxrwx   1 root   root       7 Jan 27 10:46 lib -> usr/lib
-#     lrwxrwxrwx   1 root   root       9 Jan 27 10:46 lib64 -> usr/lib64
-#     drwxr-xr-x   2 root   root    4096 Jan 27 10:46 root
-#     drwxr-xr-x   1 root   root    4096 Jan 27 10:47 run
-#     lrwxrwxrwx   1 root   root       8 Jan 27 10:46 sbin -> usr/sbin
-#     drwxrwxrwx   2 root   root    4096 Jan 27 10:46 tmp
-#     lrwxrwxrwx   1 root   root      44 Jan 27 10:46 usr -> /home/dangerzone/dangerzone-image/rootfs/usr
-#     drwxr-xr-x  11 root   root    4096 Jan 27 10:47 var
-#
-# Inner container image:
-#
-#     # ls -l /home/dangerzone/dangerzone-image/rootfs/
-#     total 12
-#     lrwxrwxrwx  1 root root    7 Jan 27 10:47 bin -> usr/bin
-#     drwxr-xr-x 43 root root 4096 Jan 27 10:46 etc
-#     lrwxrwxrwx  1 root root    7 Jan 27 10:47 lib -> usr/lib
-#     lrwxrwxrwx  1 root root    9 Jan 27 10:47 lib64 -> usr/lib64
-#     drwxr-xr-x  4 root root 4096 Jan 27 10:47 opt

-#                           SYMLINKING /USR
-#                           ===============
-#
-# It's surprisingly difficult (maybe even borderline impossible), to symlink
-# `/usr` to a different path during image build. The problem is that /usr
-# is very sensitive, and you can't manipulate it in a live system. That is, I
-# haven't found a way to do the following, or something equivalent:
-#
-#    rm -r /usr && ln -s /home/dangerzone/dangerzone-image/rootfs/usr/ /usr
-#
-# The `ln` binary, even if you specify it by its full path, cannot run
-# (probably because `ld-linux.so` can't be found). For this reason, we have
-# to create the symlinks beforehand, in a previous build stage. Then, in an
-# empty container image (scratch images), we can copy these symlinks and the
-# /usr, and stitch everything together.

-## Operating System support
-
-Dangerzone can run on various Operating Systems (OS), and has automated tests
-for most of them.
-This section explains which OS we support, how long we support each version, and
-how do we test Dangerzone against these.
-
-You can find general support information in this table, and more details in the
-following sections.
-
-(Unless specified, the architecture of the OS is AMD64)
-

-## MacOS
-
-- Download [Dangerzone 0.9.0 for Mac (Apple Silicon CPU)](https://github.com/freedomofpress/dangerzone/releases/download/v0.9.0/Dangerzone-0.9.0-arm64.dmg)
-- Download [Dangerzone 0.9.0 for Mac (Intel CPU)](https://github.com/freedomofpress/dangerzone/releases/download/v0.9.0/Dangerzone-0.9.0-i686.dmg)
-
-> [!TIP]
-> We support the releases of macOS that are still within Apple's servicing timeline. Apple usually provides security updates for the latest 3 releases, but this isn’t consistently applied and security fixes aren’t guaranteed for the non-latest releases. We are also dependent on [Docker Desktop windows support](https://docs.docker.com/desktop/setup/install/mac-install/)
-
-You can also install Dangerzone for Mac using [Homebrew](https://brew.sh/): `brew install --cask dangerzone`
-
-> **Note**: you will also need to install [Docker Desktop](https://www.docker.com/products/docker-desktop/).
-> This program needs to run alongside Dangerzone at all times, since it is what allows Dangerzone to
-> create the secure environment.
-
-## Windows
-
-- Download [Dangerzone 0.9.0 for Windows](https://github.com/freedomofpress/dangerzone/releases/download/v0.9.0/Dangerzone-0.9.0.msi)
-
-> **Note**: you will also need to install [Docker Desktop](https://www.docker.com/products/docker-desktop/).
-> This program needs to run alongside Dangerzone at all times, since it is what allows Dangerzone to
-> create the secure environment.
-
-> [!TIP]
-> We generally support Windows releases that are still within [Microsoft’s servicing timeline](https://support.microsoft.com/en-us/help/13853/windows-lifecycle-fact-sheet).
->
-> Docker sets the bottom line:
->
-> > Docker only supports Docker Desktop on Windows for those versions of Windows that are still within [Microsoft’s servicing timeline](https://support.microsoft.com/en-us/help/13853/windows-lifecycle-fact-sheet). Docker Desktop is not supported on server versions of Windows, such as Windows Server 2019 or Windows Server 2022.
-
-
-## Linux
-
-On Linux, Dangerzone uses [Podman](https://podman.io/) instead of Docker Desktop for creating
-an isolated environment. It will be installed automatically when installing Dangerzone.
-
-> [!TIP]
-> We support Ubuntu, Debian, and Fedora releases that are still within
-> their respective servicing timelines, with a few twists:
->
-> - Ubuntu: We follow upstream support with an extra cutoff date. No support for
->   versions prior to the second oldest LTS release.
-> - Fedora: We follow upstream support
-> - Debian: current stable, oldstable and LTS releases.
-
-Dangerzone is available for:
-
-- Ubuntu 25.04 (plucky)
-- Ubuntu 24.10 (oracular)
-- Ubuntu 24.04 (noble)
-- Ubuntu 22.04 (jammy)
-- Debian 13 (trixie)
-- Debian 12 (bookworm)
-- Debian 11 (bullseye)
-- Fedora 42
-- Fedora 41
-- Fedora 40
-- Tails
-- Qubes OS (beta support)

-  <summary><i>:information_source: Backport notice for Ubuntu 22.04 (Jammy) users regarding the <code>conmon</code> package</i></summary>
-  </br>
-
-  The `conmon` version that Podman uses and Ubuntu Jammy ships, has a bug
-  that gets triggered by Dangerzone
-  (more details in https://github.com/freedomofpress/dangerzone/issues/685).
-  To fix this, we provide our own `conmon` package through our APT repo, which
-  was built with the following [instructions](https://github.com/freedomofpress/maint-dangerzone-conmon/tree/ubuntu/jammy/fpf).
-  This package is essentially a backport of the `conmon` package
-  [provided](https://packages.debian.org/source/oldstable/conmon) by Debian
-  Bullseye.

-
-First, retrieve the PGP keys. The instructions differ depending on the specific
-distribution you are using:
-
-For Debian Trixie and Ubuntu Plucky (25.04), follow these instructions to
-download the PGP keys:
-
-```bash
-sudo apt-get update && sudo apt-get install sq ca-certificates -y
-sq network keyserver \
-   --server hkps://keys.openpgp.org \
-   search "DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281" \
-   --output - | sq packet dearmor fpfdz.gpg
-sudo mkdir -p /etc/apt/keyrings/
-sudo mv fpfdz.gpg /etc/apt/keyrings/fpf-apt-tools-archive-keyring.gpg
-```
-
-On other Debian-derivatives:
-
-```sh
-sudo apt-get update && sudo apt-get install gnupg2 ca-certificates -y
-sudo mkdir -p /etc/apt/keyrings/
-sudo gpg --keyserver hkps://keys.openpgp.org \
-    --no-default-keyring --keyring /etc/apt/keyrings/fpf-apt-tools-archive-keyring.gpg \
-    --recv-keys "DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281"
-```
-
-Then, on all distributions, add the URL of the repo in your APT sources:
-
-```sh
-. /etc/os-release
-echo "deb [signed-by=/etc/apt/keyrings/fpf-apt-tools-archive-keyring.gpg] \
-    https://packages.freedom.press/apt-tools-prod ${VERSION_CODENAME?} main" \
-    | sudo tee /etc/apt/sources.list.d/fpf-apt-tools.list
-```
-
-Install Dangerzone:
-
-```
-sudo apt update
-sudo apt install -y dangerzone
-```

-  </br>
-
-  This section follows the official instructions on configuring [third-party
-  Debian repos](https://wiki.debian.org/DebianRepository/UseThirdParty).
-
-  To mitigate a class of attacks against our APT repo (e.g., injecting packages
-  signed with an attacker key), we add an additional step in our instructions to
-  verify the downloaded GPG key against its fingerprint.
-
-  Aside from these protections, the user needs to be aware that Debian packages
-  run as `root` during the installation phase, so they need to place some trust
-  on our signed Debian packages. This holds for any third-party Debian repo.

-</br>
-
-After some minutes of running the above command (depending on your internet speed) you'll be asked to confirm the fingerprint of our signing key. This is to make sure that in the case our servers are compromised your computer stays safe. It should look like this:
-
-```console
---------------------------------------------------------------------------------
-Total                                           389 kB/s | 732 MB     32:07

- From       : /etc/pki/rpm-gpg/RPM-GPG-dangerzone.pub
-Is this ok [y/N]:
-```
-
-> **Note**: If it does not show this fingerprint confirmation or the fingerprint does not match, it is possible that our servers were compromised. Be distrustful and reach out to us.
-
-The `Fingerprint` should be `DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281`. For extra security, you should confirm it matches the one at the bottom of our website ([dangerzone.rocks](https://dangerzone.rocks)) and our [Mastodon account](https://fosstodon.org/@dangerzone) bio.
-
-After confirming that it matches, type `y` (for yes) and the installation should proceed.

-### Qubes OS
-
-> [!WARNING]
-> This section is for the beta version of native Qubes support. If you
-> want to try out the stable Dangerzone version (which uses containers instead
-> of virtual machines for isolation), please follow the Fedora or Debian
-> instructions and adapt them as needed.
->
-> **If you followed these instructions before October 25, 2023, please read [this security advisory](docs/advisories/2023-10-25.md).**
-> This notice will be removed with the 1.0.0 release of Dangerzone.
-
-
-> [!IMPORTANT]
-> This section will install Dangerzone in your **default template**
-> (`fedora-41` as of writing this). If you want to install it in a different
-> one, make sure to replace `fedora-41` with the template of your choice.
-
-The following steps must be completed once. Make sure you run them in the
-specified qubes.
-
-Overview of the qubes you'll create:
-
-| qube         |   type   | purpose |
-|--------------|----------|---------|
-| dz-dvm       | app qube | offline disposable template for performing conversions |
-
-#### In `dom0`:
-
-Create a **disposable**, offline app qube (`dz-dvm`), based on your default
-template. This will be the qube where the documents will be sanitized:
-
-```
-qvm-create --class AppVM --label red --template fedora-41 \
-    --prop netvm="" --prop template_for_dispvms=True \
-    --prop default_dispvm='' dz-dvm
-```
-
-Add an RPC policy (`/etc/qubes/policy.d/50-dangerzone.policy`) that will
-allow launching a disposable qube (`dz-dvm`) when Dangerzone converts a
-document, with the following contents:
-
-```
-dz.Convert         *       @anyvm       @dispvm:dz-dvm  allow
-```
-
-#### In the `fedora-41` template
-
-Install Dangerzone:
-
-```
-sudo dnf-3 config-manager --add-repo=https://packages.freedom.press/yum-tools-prod/dangerzone/dangerzone.repo
-sudo dnf install dangerzone-qubes
-```
-
-While Dangerzone gets installed, you will be prompted to accept a signing key.
-Expand the instructions in the [Verifying Dangerzone GPG key](#verifying-dangerzone-gpg-key)
-section to verify the key.
-
-Finally, shutdown the template and restart the qubes where you want to use
-Dangerzone in. Go to "Qube Settings" -> choose the "Applications" tab,
-click on "Refresh applications", and then move "Dangerzone" from the "Available"
-column to "Selected".
-
-You can now launch Dangerzone from the list of applications for your qube, and
-pass it a file to sanitize.
-
-## Tails
-
-Dangerzone is not yet available by default in Tails, but we have collaborated
-with the Tails team to offer manual
-[installation instructions](https://tails.net/doc/persistent_storage/additional_software/dangerzone/index.en.html)
-for Tails users.
-
-## Build from source
-
-If you'd like to build from source, follow the [build instructions](BUILD.md).
-
-## Verifying PGP signatures
-
-You can verify that the package you download is legitimate and hasn't been
-tampered with by verifying its PGP signature. For Windows and macOS, this step
-is optional and provides defense in depth: the Dangerzone binaries include
-operating system-specific signatures, and you can just rely on those alone if
-you'd like.
-
-### Obtaining signing key
-
-Our binaries are signed with a PGP key owned by Freedom of the Press Foundation:
-* Name: Dangerzone Release Key
-* PGP public key fingerprint `DE28 AB24 1FA4 8260 FAC9 B8BA A7C9 B385 2260 4281`
-  - You can download this key [from the keys.openpgp.org keyserver](https://keys.openpgp.org/vks/v1/by-fingerprint/DE28AB241FA48260FAC9B8BAA7C9B38522604281).
-
-_(You can also cross-check this fingerprint with the fingerprint in our
-[Mastodon page](https://fosstodon.org/@dangerzone) and the fingerprint in the
-footer of our [official site](https://dangerzone.rocks))_
-
-You must have GnuPG installed to verify signatures. For macOS you probably want
-[GPGTools](https://gpgtools.org/), and for Windows you probably want
-[Gpg4win](https://www.gpg4win.org/).
-
-### Signatures
-
-Our [GitHub Releases page](https://github.com/freedomofpress/dangerzone/releases)
-hosts the following files:
-* Windows installer (`Dangerzone-<version>.msi`)
-* macOS archives (`Dangerzone-<version>-<arch>.dmg`)
-* Container images (`container-<version>-<arch>.tar`)
-* Source package (`dangerzone-<version>.tar.gz`)
-
-All these files are accompanied by signatures (as `.asc` files). We'll explain
-how to verify them below, using `0.6.1` as an example.
-
-### Verifying
-
-Once you have imported the Dangerzone release key into your GnuPG keychain,
-downloaded the binary and ``.asc`` signature, you can verify the binary in a
-terminal like this:
-
-For the Windows binary:
-
-```
-gpg --verify Dangerzone-0.6.1.msi.asc Dangerzone-0.6.1.msi
-```
-
-For the macOS binaries (depending on your architecture):
-
-```
-gpg --verify Dangerzone-0.6.1-arm64.dmg.asc Dangerzone-0.6.1-arm64.dmg
-gpg --verify Dangerzone-0.6.1-i686.dmg.asc Dangerzone-0.6.1-i686.dmg
-```
-
-For the container images:
-
-```
-gpg --verify container-0.6.1-i686.tar.asc container-0.6.1-i686.tar
-```
-
-For the source package:
-
-```
-gpg --verify dangerzone-0.6.1.tar.gz.asc dangerzone-0.6.1.tar.gz
-```
-
-We also hash all the above files with SHA-256, and provide a list of these
-hashes as a separate file (`checksums-0.6.1.txt`). This file is signed as well,
-and the signature is embedded within it. You can download this file and verify
-it with:
-
-```
-gpg --verify checksums.txt
-```
-
-The expected output looks like this:
-
-```
-gpg: Signature made Mon Apr 22 09:29:22 2024 PDT
-gpg:                using RSA key 04CABEB5DD76BACF2BD43D2FF3ACC60F62EA51CB
-gpg: Good signature from "Dangerzone Release Key <dangerzone-release-key@freedom.press>" [unknown]
-gpg: WARNING: This key is not certified with a trusted signature!
-gpg:          There is no indication that the signature belongs to the owner.
-Primary key fingerprint: DE28 AB24 1FA4 8260 FAC9  B8BA A7C9 B385 2260 4281
-     Subkey fingerprint: 04CA BEB5 DD76 BACF 2BD4  3D2F F3AC C60F 62EA 51CB
-```
-
-If you don't see `Good signature from`, there might be a problem with the
-integrity of the file (malicious or otherwise), and you should not install the
-package.
-
-The `WARNING:` shown above, is not a problem with the package, it only means you
-haven't defined a level of "trust" for Dangerzone's PGP key.
-
-If you want to learn more about verifying PGP signatures, the guides for
-[Qubes OS](https://www.qubes-os.org/security/verifying-signatures/) and the
-[Tor Project](https://support.torproject.org/tbb/how-to-verify-signature/) may
-be useful.

-
-  A secondary benefit of defending all users' freedom is that

-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.

-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published
-    by the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see
-<https://www.gnu.org/licenses/>.

-## QA
-
-To ensure that new releases do not introduce regressions, and support existing
-and newer platforms, we have to test that the produced packages work as expected.
-
-Check the following:
-
-- [ ] Make sure that the tip of the `main` branch passes the CI tests.
-- [ ] Make sure that the Apple account has a valid application password and has
-      agreed to the latest Apple terms (see [macOS release](#macos-release)
-      section).
-
-Because it is repetitive, we wrote a script to help with the QA.
-It can run the tasks for you, pausing when it needs manual intervention.
-
-You can run it with a command like:
-
-```bash
-poetry run ./dev_scripts/qa.py {distro}-{version}
-```
-
-### The checklist
-
-- [ ] Create a test build in Windows and make sure it works:
-  - [ ] Check if the suggested Python version is still supported.
-  - [ ] Create a new development environment with Poetry.
-  - [ ] Build the container image and ensure the development environment uses
-    the new image.
-  - [ ] Download the OCR language data using `./install/common/download-tessdata.py`
-  - [ ] Run the Dangerzone tests.
-  - [ ] Build and run the Dangerzone .exe
-  - [ ] Test some QA scenarios (see [Scenarios](#Scenarios) below).

-    the new image.
-  - [ ] Download the OCR language data using `./install/common/download-tessdata.py`
-  - [ ] Run the Dangerzone tests.
-  - [ ] Create and run an app bundle.
-  - [ ] Test some QA scenarios (see [Scenarios](#Scenarios) below).
-- [ ] Create a test build in macOS (M1/2 CPU) and make sure it works:
-  - [ ] Check if the suggested Python version is still supported.
-  - [ ] Create a new development environment with Poetry.
-  - [ ] Build the container image and ensure the development environment uses
-    the new image.
-  - [ ] Download the OCR language data using `./install/common/download-tessdata.py`
-  - [ ] Run the Dangerzone tests.
-  - [ ] Create and run an app bundle.
-  - [ ] Test some QA scenarios (see [Scenarios](#Scenarios) below).
-- [ ] Create a test build in the most recent Ubuntu LTS platform (Ubuntu 24.04
-  as of writing this) and make sure it works:
-  - [ ] Create a new development environment with Poetry.
-  - [ ] Build the container image and ensure the development environment uses
-    the new image.
-  - [ ] Download the OCR language data using `./install/common/download-tessdata.py`

-- [ ] Create a test build in the most recent Qubes Fedora template (Fedora 40 as
-  of writing this) and make sure it works:
-  - [ ] Create a new development environment with Poetry.
-  - [ ] Run the Dangerzone tests.
-  - [ ] Create a Qubes .rpm package and install it system-wide.
-  - [ ] Ensure that the Dangerzone application appears in the "Applications"
-    tab.
-  - [ ] Test some QA scenarios (see [Scenarios](#Scenarios) below) and make sure
-    they spawn disposable qubes.
-
-### Scenarios
-
-#### 1. Dangerzone correctly identifies that Docker/Podman is not installed
-
-_(Only for MacOS / Windows)_
-
-Temporarily hide the Docker/Podman binaries, e.g., rename the `docker` /
-`podman` binaries to something else. Then run Dangerzone. Dangerzone should
-prompt the user to install Docker/Podman.
-
-#### 2. Dangerzone correctly identifies that Docker is not running
-
-_(Only for MacOS / Windows)_
-
-Stop the Docker Desktop application. Then run Dangerzone. Dangerzone should
-prompt the user to start Docker Desktop.
-
-
-#### 3. Updating Dangerzone handles external state correctly.
-
-_(Applies to Windows/MacOS)_
-
-Install the previous version of Dangerzone, downloaded from the website.
-
-Open the Dangerzone application and enable some non-default settings.
-**If there are new settings, make sure to change those as well**.
-
-Close the Dangerzone application and get the container image for that
-version. For example:
-
-```
-$ docker images dangerzone.rocks/dangerzone
-REPOSITORY                   TAG         IMAGE ID      CREATED       SIZE
-dangerzone.rocks/dangerzone  <tag>       <image ID>    <date>        <size>
-```
-
-Then run the version under QA and ensure that the settings remain changed.
-
-Afterwards check that new docker image was installed by running the same command
-and seeing the following differences:
-
-```
-$ docker images dangerzone.rocks/dangerzone
-REPOSITORY                   TAG         IMAGE ID        CREATED       SIZE
-dangerzone.rocks/dangerzone  <other tag> <different ID>  <newer date>  <different size>
-```
-
-#### 4. Dangerzone successfully installs the container image
-
-_(Only for Linux)_
-
-Remove the Dangerzone container image from Docker/Podman. Then run Dangerzone.
-Dangerzone should install the container image successfully.
-
-#### 5. Dangerzone retains the settings of previous runs
-
-Run Dangerzone and make some changes in the settings (e.g., change the OCR
-language, toggle whether to open the document after conversion, etc.). Restart
-Dangerzone. Dangerzone should show the settings that the user chose.
-
-#### 6. Dangerzone reports failed conversions
-
-Run Dangerzone and convert the `tests/test_docs/sample_bad_pdf.pdf` document.
-Dangerzone should fail gracefully, by reporting that the operation failed, and
-showing the following error message:
-
-> The document format is not supported
-
-#### 7. Dangerzone succeeds in converting multiple documents
-
-Run Dangerzone against a list of documents, and tick all options. Ensure that:
-* Conversions take place sequentially.
-* Attempting to close the window while converting asks the user if they want to
-  abort the conversions.
-* Conversions are completed successfully.
-* Conversions show individual progress in real-time (double-check for Qubes).
-* _(Only for Linux)_ The resulting files open with the PDF viewer of our choice.
-* OCR seems to have detected characters in the PDF files.
-* The resulting files have been saved with the proper suffix, in the proper
-  location.
-* The original files have been saved in the `unsafe/` directory.
-
-#### 8. Dangerzone is able to handle drag-n-drop
-
-Run Dangerzone against a set of documents that you drag-n-drop. Files should be
-added and conversion should run without issue.
-
-> [!TIP]
-> On our end-user container environments for Linux, we can start a file manager
-> with `thunar &`.
-
-#### 9. Dangerzone CLI succeeds in converting multiple documents
-
-_(Only for Windows and Linux)_
-
-Run Dangerzone CLI against a list of documents. Ensure that conversions happen
-sequentially, are completed successfully, and we see their progress.
-
-#### 10. Dangerzone can open a document for conversion via right-click -> "Open With"
-
-_(Only for Windows, MacOS and Qubes)_
-
-Go to a directory with office documents, right-click on one, and click on "Open
-With". We should be able to open the file with Dangerzone, and then convert it.
-
-#### 11. Dangerzone shows helpful errors for setup issues on Qubes
-
-_(Only for Qubes)_
-
-Check what errors does Dangerzone throw in the following scenarios. The errors
-should point the user to the Qubes notifications in the top-right corner:
-
-1. The `dz-dvm` template does not exist. We can trigger this scenario by
-   temporarily renaming this template.
-2. The Dangerzone RPC policy does not exist. We can trigger this scenario by
-   temporarily renaming the `dz.Convert` policy.
-3. The `dz-dvm` disposable Qube cannot start due to insufficient resources. We
-   can trigger this scenario by temporarily increasing the minimum required RAM
-   of the `dz-dvm` template to more than the available amount.

 - Sandboxes don't have network access, so if a malicious document can compromise one, it can't phone home
-- Sandboxes use [gVisor](https://gvisor.dev/), an application kernel written in Go, that implements a substantial portion of the Linux system call interface.
 - Dangerzone can optionally OCR the safe PDFs it creates, so it will have a text layer again
 - Dangerzone compresses the safe PDF to reduce file size
 - After converting, Dangerzone lets you open the safe PDF in the PDF viewer of your choice, which allows you to open PDFs and office docs in Dangerzone by default so you never accidentally open a dangerous document

-## FAQ
-
-### Has Dangerzone received a security audit?
-
-Yes, Dangerzone received its [first security audit](https://freedom.press/news/dangerzone-receives-favorable-audit/) by [Include Security](https://includesecurity.com/) in December 2023. The audit was generally favorable, as it didn't identify any high-risk findings, except for 3 low-risk and 7 informational findings.
-
-### "I'm experiencing an issue while using Dangerzone."
-
-Dangerzone gets updates to improve its features _and_ to fix problems. So, updating may be the simplest path to resolving the issue which brought you here. Here is how to update:
-
-1. Check which version of Dangerzone you are currently using: run Dangerzone, then look for a series of numbers to the right of the logo within the app. The format of the numbers will look similar to `0.4.1`
-2. Now find the latest available version of Dangerzone: go to the [download page](https://dangerzone.rocks/#downloads). Look for the version number displayed. The number will be using the same format as in Step 1.
-3. Is the version on the Dangerzone download page higher than the version of your installed app? Go ahead and update.
-
-### Can I use Podman Desktop?
-
-Yes! We've introduced [experimental support for Podman Desktop](https://github.com/freedomofpress/dangerzone/blob/main/docs/podman-desktop.md) on Windows and macOS.

 # Release instructions
 
-This section documents how we currently release Dangerzone for the different distributions we support.
+This section documents the release process. Unless you're a dangerzone developer making a release, you'll probably never need to follow it.
 
-## Pre-release
+## Changelog, version, and signed git tag
 
-Here is a list of tasks that should be done before issuing the release:
+Before making a release, all of these should be complete:
 
-- [ ] Create a new issue named **QA and Release for version \<VERSION\>**, to track the general progress.
-      You can generate its content with the the `poetry run ./dev_scripts/generate-release-tasks.py` command.
-- [ ] [Add new Linux platforms and remove obsolete ones](https://github.com/freedomofpress/dangerzone/blob/main/RELEASE.md#add-new-linux-platforms-and-remove-obsolete-ones)
-- [ ] Bump the Python dependencies using `poetry lock`
-- [ ] Check for new [WiX releases](https://github.com/wixtoolset/wix/releases) and update it if needed
 - [ ] Update `version` in `pyproject.toml`
 - [ ] Update `share/version.txt`
-- [ ] Update the "Version" field in `install/linux/dangerzone.spec`
+- [ ] Update version and download links in `README.md`, and screenshot if necessary
-- [ ] Bump the Debian version by adding a new changelog entry in `debian/changelog`
-- [ ] [Bump the minimum Docker Desktop versions](https://github.com/freedomofpress/dangerzone/blob/main/RELEASE.md#bump-the-minimum-docker-desktop-version) in `isolation_provider/container.py`
-- [ ] Bump the dates and versions in the `Dockerfile`
-- [ ] Update the download links in our `INSTALL.md` page to point to the new version (the download links will be populated after the release)
-- [ ] Update screenshot in `README.md`, if necessary
 - [ ] CHANGELOG.md should be updated to include a list of all major changes since the last release
-- [ ] A draft release should be created. Copy the release notes text from the template at [`docs/templates/release-notes`](https://github.com/freedomofpress/dangerzone/tree/main/docs/templates/)
+- [ ] In `.circleci/config.yml`, add new platforms and remove obsolete platforms
-- [ ] Send the release notes to editorial for review
+- [ ] Create a test build in Windows and make sure it works
-- [ ] Do the QA tasks
+- [ ] Create a test build in mcaOS and make sure it works
+- [ ] There must be a PGP-signed git tag for the version, e.g. for dangerzone 0.1.0, the tag must be `v0.1.0`
 
-## Add new Linux platforms and remove obsolete ones
+Before making a release, verify the release git tag:
 
-Our currently supported Linux OSes are Debian, Ubuntu, Fedora (we treat Qubes OS
+```
-as a special case of Fedora, release-wise). For each of these platforms, we need
+git fetch
-to check if a new version has been added, or if an existing one is now EOL
+git tag -v v$VERSION
-(https://endoflife.date/ is handy for this purpose).
+```
 
-In case of a new version (beta, RC, or official release):
+If the tag verifies successfully and check it out:
 
-1. Add it in our CI workflows, to test if that version works.
+```
-   * See `.circleci/config.yml` and `.github/workflows/ci.yml`, as well as
+git checkout v$VERSION
-     `dev_scripts/env.py` and `dev_scripts/qa.py`.
+```
-2. Do a test of this version locally with `dev_scripts/qa.py`. Focus on the
-   GUI part, since the basic functionality is already tested by our CI
-   workflows.
-3. Add the new version in our `INSTALL.md` document, and drop a line in our
-   `CHANGELOG.md`.
-4. If that version is a new stable release, update the `RELEASE.md` and
-   `BUILD.md` files where necessary.
-4. Send a PR with the above changes.
 
-In case of the removal of a version:
+## macOS release
 
-1. Remove any mention to this version from our repo.
+To make a macOS release, go to macOS build machine:
-   * Consult the previous paragraph, but also `grep` your way around.
-2. Add a notice in our `CHANGELOG.md` about the version removal.
-
-## Bump the minimum Docker Desktop version
-
-We embed the minimum docker desktop versions inside Dangerzone, as an incentive for our macOS and Windows users to upgrade to the latests version.
-
-You can find the latest version at the time of the release by looking at [their release notes](https://docs.docker.com/desktop/release-notes/)
-
-## Large Document Testing
-
-Parallel to the QA process, the release candidate should be put through the large document tests in a dedicated machine to run overnight.
-
-Follow the instructions in `docs/developer/TESTING.md` to run the tests.
-
-These tests will identify any regressions or progression in terms of document coverage.
-
-## Release
-
-Once we are confident that the release will be out shortly, and doesn't need any more changes:
-
-- [ ] Create a PGP-signed git tag for the version, e.g., for dangerzone `v0.1.0`:
-
-  ```bash
-  git tag -s v0.1.0
-  git push origin v0.1.0
-  ```
-  **Note**: release candidates are suffixed by `-rcX`.
-
-> [!IMPORTANT]
-> Because we don't have [reproducible builds](https://github.com/freedomofpress/dangerzone/issues/188)
-> yet, building the Dangerzone container image in various platforms would lead
-> to different container image IDs / hashes, due to different timestamps. To
-> avoid this issue, we should build the final container image for x86_64
-> architectures on **one** platform, and then copy it to the rest of the
-> platforms, before creating our .deb / .rpm / .msi / app bundles.
-
-### macOS Release
-
-> [!TIP]
-> You can automate these steps from your macOS terminal app with:
->
-> ```
-> export APPLE_ID=<email>
-> make build-macos-intel  # for Intel macOS
-> make build-macos-arm    # for Apple Silicon macOS
-> ```
-
-The following needs to happen for both Silicon and Intel chipsets.
-
-#### Initial Setup
 
 - Build machine must have:
-  - Apple-trusted `Developer ID Application: Freedom of the Press Foundation (94ZZGGGJ3W)` code-signing certificates installed
+  - macOS 10.14
-- Apple account must have:
+  - Apple-trusted `Developer ID Application: FIRST LOOK PRODUCTIONS, INC.` and `Developer ID Installer: FIRST LOOK PRODUCTIONS, INC.` code-signing certificates installed
-  - A valid application password for `notarytool` in the Keychain. You can verify
+  - An app-specific Apple ID password saved in the login keychain called `flockagent-notarize`
-    this by running: `xcrun notarytool history --apple-id "<email>" --keychain-profile "dz-notarytool-release-key"`. If you don't find it, you can add it to the Keychain by running
+- Verify and checkout the git tag for this release
-    `xcrun notarytool store-credentials dz-notarytool-release-key --apple-id <email> --team-id <team ID>`
+- Run `poetry install`
-    with the respective `email` and `team ID` (the latter can be obtained [here](https://developer.apple.com/help/account/manage-your-team/locate-your-team-id))
+- Run `poetry run ./install/macos/build_app.py --with-codesign`; this will make `dist/Dangerzone.dmg`
-  - Agreed to any new terms and conditions. You can find those if you visit
+- Notarize it: `xcrun altool --notarize-app --primary-bundle-id "media.firstlook.dangerzone" -u "micah@firstlook.org" -p "@keychain:dangerzone-notarize" --file dist/Dangerzone.dmg`
-    https://developer.apple.com and login with the proper Apple ID.
+- Wait for it to get approved, check status with: `xcrun altool --notarization-history 0 -u "micah@firstlook.org" -p "@keychain:dangerzone-notarize"`
+- (If it gets rejected, you can see why with: `xcrun altool --notarization-info [RequestUUID] -u "micah@firstlook.org" -p "@keychain:dangerzone-notarize"`)
+- After it's approved, staple the ticket: `xcrun stapler staple dist/Dangerzone.dmg`
 
-#### Releasing and Signing
+This process ends up with the final file:
 
-Here is what you need to do:
+```
+dist/Dangerzone.dmg
+```
 
-- [ ] Verify and install the latest supported Python version from
+Rename `Dangerzone.dmg` to `Dangerzone-$VERSION.dmg`.
-  [python.org](https://www.python.org/downloads/macos/) (do not use the one from
-  brew as it is known to [cause issues](https://github.com/freedomofpress/dangerzone/issues/471))
 
-- [ ] Checkout the dependencies, and clean your local copy:
+## Windows release
 
-  ```bash
+To make a Windows release, go to the Windows build machine:
 
-  # In case of a new Python installation or minor version upgrade, e.g., from
+- Build machine should be running Windows 10, and have the Windows codesigning certificate installed
-  # 3.11 to 3.12, reinstall Poetry
+- Verify and checkout the git tag for this release
-  python3 -m pip install poetry
+- Run `poetry install`
-
+- Run `poetry shell`, then `cd ..\pyinstaller`, `python setup.py install`, `exit`
-  # You can verify the correct Python version is used
+- Run `poetry run install\windows\step1-build-exe.bat`
-  poetry debug info
+- Open a second command prompt _as an administratror_, cd to the dangerzone directory, and run: `install\windows\step2-make-symlink.bat`
-
+- Back in the first command prompt, run: `poetry run install\windows\step3-build-installer.bat`
-  # Replace with the actual version
+- When you're done you will have `dist\Dangerzone.msi`
-  export DZ_VERSION=$(cat share/version.txt)
-
-  # Verify and checkout the git tag for this release:
-  git checkout -f v$VERSION
-
-  # Clean the git repository
-  git clean -df
-
-  # Clean up the environment
-  poetry env remove --all
-
-  # Install the dependencies
-  poetry sync
-  ```
-
-- [ ] Build the container image and the OCR language data
-
-  ```bash
-  poetry run ./install/common/build-image.py
-  poetry run ./install/common/download-tessdata.py
-
-  # Copy the container image to the assets folder
-  cp share/container.tar ~dz/release-assets/$VERSION/dangerzone-$VERSION-arm64.tar
-  cp share/image-id.txt ~dz/release-assets/$VERSION/.
-  ```
-
-- [ ] Build the app bundle
-
-  ```bash
-  poetry run ./install/macos/build-app.py
-  ```
-
-- [ ] Sign the application bundle, and notarize it
-
-  You need to run this command as the account that has access to the code signing certificate
-
-  This command assumes that you have created, and stored in the Keychain, an
-  application password associated with your Apple Developer ID, which will be
-  used specifically for `notarytool`.
-
-  ```bash
-  # Sign the .App and make it a .dmg
-  poetry run ./install/macos/build-app.py --only-codesign
-
-  # Notarize it. You must run this command from the MacOS UI
-  # from a terminal application.
-  xcrun notarytool submit ./dist/Dangerzone.dmg --apple-id $APPLE_ID --keychain-profile "dz-notarytool-release-key" --wait && xcrun stapler staple dist/Dangerzone.dmg
-
-  # Copy the .dmg to the assets folder
-  ARCH=$(uname -m)
-  if [ "$ARCH" = "x86_64" ]; then

-### Windows Release
-
-The Windows release is performed in a Windows 11 virtual machine (as opposed to a physical one).
-
-#### Initial Setup
-
-- Download a VirtualBox VM image for Windows from here: https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ and import it into VirtualBox. Also install the Oracle VM VirtualBox Extension Pack.
-- Install updates
-- Install git for Windows from https://git-scm.com/download/win, and clone the dangerzone repo
-- Follow the Windows build instructions in `BUILD.md`, except:
-  - Don't install Docker Desktop (it won't work without nested virtualization)
-  - Install the Windows SDK from here: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ and add `C:\Program Files (x86)\Microsoft SDKs\ClickOnce\SignTool` to the path (you'll need it for `signtool.exe`)
-  - You'll also need the Windows codesigning certificate installed on the VM
-
-#### Releasing and Signing
-
-- [ ] Checkout the dependencies, and clean your local copy:
-  ```bash
-  # In case of a new Python installation or minor version upgrade, e.g., from
-  # 3.11 to 3.12, reinstall Poetry
-  python3 -m pip install poetry
-
-  # You can verify the correct Python version is used
-  poetry debug info
-
-  # Replace with the actual version
-  export DZ_VERSION=$(cat share/version.txt)
-
-  # Verify and checkout the git tag for this release:
-  git checkout -f v$VERSION
-
-  # Clean the git repository
-  git clean -df
-
-  # Clean up the environment
-  poetry env remove --all
-
-  # Install the dependencies
-  poetry sync
-  ```
-
-- [ ] Copy the container image into the VM
-  > [!IMPORTANT]
-  > Instead of running `python .\install\windows\build-image.py` in the VM, run the build image script on the host (making sure to build for `linux/amd64`). Copy `share/container.tar` and `share/image-id.txt` from the host into the `share` folder in the VM.
-- [ ] Run `poetry run .\install\windows\build-app.bat`
-- [ ] When you're done you will have `dist\Dangerzone.msi`
 
 Rename `Dangerzone.msi` to `Dangerzone-$VERSION.msi`.
 
-### Linux release
+## Linux release
 
-> [!TIP]
+Linux binaries are automatically built and deployed to repositories when a new tag is pushed.
-> You can automate these steps from any Linux distribution with:
->
-> ```
-> make build-linux
-> ```
->
-> You can then add the created artifacts to the appropriate APT/YUM repo.
 
-Below we explain how we build packages for each Linux distribution we support.
+## Publishing the release
 
-#### Debian/Ubuntu
+To publish the release:
 
-Because the Debian packages do not contain compiled Python code for a specific
+- Create a new release on GitHub, put the changelog in the description of the release, and upload the macOS and Windows installers
-Python version, we can create a single Debian package and use it for all of our
+- Update the [Installing Dangerzone](https://github.com/firstlookmedia/dangerzone/wiki/Installing-Dangerzone) wiki page
-Debian-based distros.
+- Update the [Dangerzone website](https://github.com/firstlookmedia/dangerzone.rocks) to link to the new installers
-
-Create a Debian Bookworm development environment. You can [follow the
-instructions in our build section](https://github.com/freedomofpress/dangerzone/blob/main/BUILD.md#debianubuntu),
-or create your own locally with:
-
-```sh
-# Create and run debian bookworm development environment
-./dev_scripts/env.py --distro debian --version bookworm build-dev
-./dev_scripts/env.py --distro debian --version bookworm run --dev bash
-
-# Build the latest container
-./dev_scripts/env.py --distro debian --version bookworm run --dev bash -c "cd dangerzone && poetry run ./install/common/build-image.py"
-
-# Create a .deb
-./dev_scripts/env.py --distro debian --version bookworm run --dev bash -c "cd dangerzone && ./install/linux/build-deb.py"
-```
-
-Publish the .deb under `./deb_dist` to the
-[`freedomofpress/apt-tools-prod`](https://github.com/freedomofpress/apt-tools-prod)
-repo, by sending a PR. Follow the instructions in that repo on how to do so.
-
-#### Fedora
-
-> **NOTE**: This procedure will have to be done for every supported Fedora version.
->
-> In this section, we'll use Fedora 41 as an example.
-
-Create a Fedora development environment. You can [follow the
-instructions in our build section](https://github.com/freedomofpress/dangerzone/blob/main/BUILD.md#fedora),
-or create your own locally with:
-
-```sh
-./dev_scripts/env.py --distro fedora --version 41 build-dev
-
-# Build the latest container (skip if already built):
-./dev_scripts/env.py --distro fedora --version 41 run --dev bash -c "cd dangerzone && poetry run ./install/common/build-image.py"
-
-# Create a .rpm:
-./dev_scripts/env.py --distro fedora --version 41 run --dev bash -c "cd dangerzone && ./install/linux/build-rpm.py"
-```
-
-Publish the .rpm under `./dist` to the
-[`freedomofpress/yum-tools-prod`](https://github.com/freedomofpress/yum-tools-prod) repo, by sending a PR. Follow the instructions in that repo on how to do so.
-
-#### Qubes
-
-Create a .rpm for Qubes:
-
-```sh
-./dev_scripts/env.py --distro fedora --version 41 run --dev bash -c "cd dangerzone && ./install/linux/build-rpm.py --qubes"
-```
-
-and similarly publish it to the [`freedomofpress/yum-tools-prod`](https://github.com/freedomofpress/yum-tools-prod)
-repo.
-
-## Publishing the Release
-
-To publish the release, you can follow these steps:
-
-- [ ] Create an archive of the Dangerzone source in `tar.gz` format:
-  ```bash
-  export VERSION=$(cat share/version.txt)
-  git archive --format=tar.gz -o dangerzone-${VERSION:?}.tar.gz --prefix=dangerzone/ v${VERSION:?}
-  ```
-
-- [ ] Run container scan on the produced container images (some time may have passed since the artifacts were built)
-  ```bash
-  docker pull anchore/grype:latest
-  docker run --rm -v ./share/container.tar:/container.tar anchore/grype:latest /container.tar
-  ```
-
-- [ ] Collect the assets in a single directory, calculate their SHA-256 hashes, and sign them.
-  There is an `./dev_scripts/sign-assets.py` script to automate this task.
-
-  **Important:** Before running the script, make sure that it's the same container images as
-  the ones that are shipped in other platforms (see our [Pre-release](#Pre-release) section)
-
-  ```bash
-  # Sign all the assets
-  ./dev_scripts/sign-assets.py ~/release-assets/$VERSION/github --version $VERSION
-  ```
-
-- [ ] Upload all the assets to the draft release on GitHub.
-  ```bash
-  find ~/release-assets/$VERSION/github | xargs -n1 ./dev_scripts/upload-asset.py --token ~/token --draft
-  ```
-
-- [ ] Update the [Dangerzone website](https://github.com/freedomofpress/dangerzone.rocks) to link to the new installers.
-- [ ] Update the brew cask release of Dangerzone with a [PR like this one](https://github.com/Homebrew/homebrew-cask/pull/116319)
-- [ ] Update version and links to our installation instructions (`INSTALL.md`) in `README.md`
-
-## Post-release
-
-- [ ] Toot release announcement on our mastodon account @dangerzone@fosstodon.org
-- [ ] Extend the `check_repos.yml` CI test for the newly added platforms

-          running gVisor.

-          (see https://github.com/freedomofpress/dangerzone/issues/880).
-        * Set a custom seccomp policy for every container engine, since the `ptrace(2)`
-          system call is forbidden by some.
-
-        For Podman specifically, where applicable, we also add the following:
-        * Do not log the container's output.
-        * Do not map the host user to the container, with `--userns nomap` (available

-
-        Qubes does not offer a way out of the box to terminate disposable Qubes from
-        domU [1]. Our best bet is to close the standard streams of the process, and hope
-        that the disposable qube will attempt to read/write to them, and thus receive an
-        EOF.
-
-        There are two ways we can do the above; close the standard streams explicitly,
-        or terminate the process. The problem with the latter is that terminating
-        `qrexec-client-vm` happens immediately, and we no longer have a way to learn if
-        the disposable qube actually terminated. That's why we prefer closing the
-        standard streams explicitly, so that we can afterwards use `Popen.wait()` to
-        learn if the qube terminated.
-
-        Note that we don't close the stderr stream because we want to read debug logs
-        from it. In the rare case where a qube cannot terminate because it's stuck
-        writing at stderr (this is not the expected behavior), we expect that the
-        process will still be forcefully killed after the soft termination timeout
-        expires.

-# Security Advisory 2023-10-25
-
-For users testing our [new Qubes integration (beta)](https://github.com/freedomofpress/dangerzone/blob/main/INSTALL.md#qubes-os), please note that our instructions were missing a configuration detail for disposable VMs which is necessary to fully harden the configuration.
-
-These instructions apply to users who followed the setup instructions **before October 25, 2023**.
-
-**What you need to do:** run the following command in dom0:
-
-```bash
-qvm-prefs dz-dvm default_dispvm ''
-```
-
-**Explanation**: In Qubes OS, the default template for disposable VMs is network-connected. For this reason, we instruct users to create their own disposable VM (`dz-dvm`). However, adversaries with the ability to execute commands on `dz-dvm` would also be able open new disposable VMs with the default settings. By setting the default_dispvm to "none" we prevent this bypass.

-Dangerzone has some automated testing under `tests/`.
-
-The following assumes that you have already setup the development environment.
-
-## Run tests
-
-Unit / integration tests are run with:
-
-```bash
-poetry run make test
-```
-
-## Run large tests
-
-We also have a larger set of tests that can take a day or more to run, where we evaluate the completeness of Dangerzone conversions.
-
-```bash
-poetry run make test-large
-```
-
-### Test report generation
-After running the large tests, a report is stored under `tests/test_docs_large/results/junit/` and it is composed of the JUnit XML file describing the pytest run.
-
-This report can be analysed for errors. It is obtained by running:
-
-```bash
-cd tests/docs_test_large
-make report
-```
-
-If you want to run the report on some historical test result, you can call:
-
-```bash

-# Using the Doit Automation Tool
-
-Developers can use the [Doit](https://pydoit.org/) automation tool to create
-release artifacts. The purpose of the tool is to automate the manual release
-instructions in `RELEASE.md` file. Not everything is automated yet, since we're
-still experimenting with this tool. You can find our task definitions in this
-repo's `dodo.py` file.
-
-## Why Doit?
-
-We picked Doit out of the various tools out there for the following reasons:
-
-* **Pythonic:** The configuration file and tasks can be written in Python. Where
-  applicable, it's easy to issue shell commands as well.
-* **File targets:** Doit borrows the file target concept from Makefiles. Tasks
-  can have file dependencies, and targets they build. This makes it easy to
-  define a dependency graph for tasks.
-* **Hash-based caching:** Unlike Makefiles, doit does not look at the
-  modification timestamp of source/target files, to figure out if it needs to
-  run them.  Instead, it hashes those files, and will run a task only if the
-  hash of a file dependency has changed.
-* **Parallelization:** Tasks can be run in parallel with the `-n` argument,
-  which is similar to `make`'s `-j` argument.
-
-## How to Doit?
-
-First, enter your Poetry shell. Then, make sure that your environment is clean,
-and you have ample disk space. You can run:
-
-```bash
-doit clean --dry-run  # if you want to see what would happen
-doit clean  # you'll be asked to cofirm that you want to clean everything
-```
-
-Finally, you can build all the release artifacts with `doit`, or a specific task
-with:
-
-```
-doit <task>
-```
-
-## Tips and tricks
-
-* You can run `doit list --all -s` to see the full list of tasks, their
-  dependencies, and whether they are up to date (U) or will run (R). Note that
-  certain small tasks are always configured to run.
-* You can run `doit info <task>` to see which dependencies are missing.
-* You can pass the following environment variables to the script, in order to
-  affect some global parameters:
-  - `CONTAINER_RUNTIME`: The container runtime to use. Either `podman` (default)
-    or `docker`.
-  - `RELEASE_DIR`: Where to store the release artifacts. Default path is
-    `~/release-assets/<version>`
-  - `APPLE_ID`: The Apple ID to use when signing/notarizing the macOS DMG.

-# Create Dangerzone environments
-
-The `dev_scripts/env.py` script creates environments where a user can run
-Dangerzone, allows the user to run arbitrary commands in these environments, as
-well as run Dangerzone (nested containerization).
-
-It supports two types of environments:
-
-1. Dev environment. This environment has developer tools, necessary for
-   Dangerzone, baked in. Also, it mounts the Dangerzone source under
-   `/home/user/dangerzone` in the container. The developer can then run
-   Dangerzone from source, with `poetry run ./dev_scripts/dangerzone`.
-2. End-user environment. This environment has only Dangerzone installed in it,
-   from the .deb/.rpm package that we have created. For convenience, it also has
-   the Dangerzone source mounted under `/home/user/dangerzone`, but it lacks
-   Poetry and other build tools. The developer can run Dangerzone there with
-   `dangerzone`. This environment is the most vanilla Dangerzone environment,
-   and should be closer to the end user's environment, than the development
-   environment.
-
-Each environment corresponds to a Dockerfile, which is generated on the fly. The
-developer can see this Dockerfile by passing `--show-dockerfile`.
-
-For usage information, run `./dev_scripts/env.py --help`.
-
-## Nested containerization
-
-Since the Dangerzone environments are containers, this means that the Podman
-containers that Dangerzone creates have to be nested containers. This has some
-challenges that we will highlight below:
-
-1. Containers typically only have a subset of syscalls allowed, and sometimes
-   only for specific arguments. This happens with the use of
-   [seccomp filters](https://docs.docker.com/engine/security/seccomp/). For
-   instance, in Docker, the `clone` syscall is limited in containers and cannot
-   create new namespaces
-   (https://docs.docker.com/engine/security/seccomp/#significant-syscalls-blocked-by-the-default-profile). For testing/development purposes, we can get around this limitation
-   by disabling the seccomp filters for the external container with
-   `--security-opt seccomp=unconfined`. This has the same effect as developing
-   Dangerzone locally, so it should probably be sufficient for now.
-
-2. While Linux supports nested namespaces, we need extra handling for nested
-   user namespaces. By default, the configuration for each user namespace (see
-   [`man login.defs`](https://man7.org/linux/man-pages/man5/login.defs.5.html)
-   is to reserve 65536 UIDs/GIDs, starting from UID/GID 100000. This works fine
-   for the first container, but can't work for the nested container, since it
-   doesn't have enough UIDs/GIDs to refer to UID 100000. Our solution to this is
-   to restrict the number of UIDs/GIDs allowed in the nested container to 2000,
-   which should be enough to run `podman` in it.
-
-3. Containers also restrict the capabilities (see
-   [`man capabilities`](https://man7.org/linux/man-pages/man7/capabilities.7.html))
-   of the processes that run in them. By default, containers do not have mount
-   capabilities, since it requires `CAP_SYS_ADMIN`, which effectively
-   [makes the process root](https://lwn.net/Articles/486306/) in the specific
-   user namespace. In our case, we have to give the Dangerzone environment this
-   capability, since it will have to mount directories in Podman containers. For
-   this reason, as well as some extra things we bumped into during development,
-   we pass `--privileged` when creating the Dangerzone environment, which
-   includes the `CAP_SYS_ADMIN` capability.
-
-## GUI containerization
-
-Running a GUI app in a container is a tricky subject for multi-platform apps. In
-our case, we deal specifically with Linux environments, so we can target just
-this platform.
-
-To understand how a GUI app can draw in the user's screen from within a
-container, we must first understand how it does so outside the container. In
-Unix-like systems, GUI apps act like
-[clients to a display server](https://wayland.freedesktop.org/architecture.html).
-The most common display server implementation is X11, and the runner-up is
-Wayland. Both of these display servers share some common traits, mainly that
-they use Unix domain sockets as a way of letting clients communicate with them.
-
-So, this gives us the answer on how one can run a containerized GUI app; they
-can simply mount the Unix Domain Socket in the container. In practice this is
-more nuanced, for two reasons:
-
-1. Wayland support is not that mature on Linux, so we need to
-   [set some extra environment variables](https://github.com/mviereck/x11docker/wiki/How-to-provide-Wayland-socket-to-docker-container). To simplify things, we will target
-   X11 / XWayland hosts, which are the majority of the Linux OSes out there.
-2. Sharing the Unix Domain socket does not allow the client to talk to the
-   display server, for security reasons. In order to allow the client, we need
-   to mount a magic cookie stored in a file pointed at by the `$XAUTHORITY`
-   envvar. Else, we can use `xhost`, which is considered slightly more dangerous
-   for multi-user environments.
-
-## Caching and Reproducibility
-
-In order to build Dangerzone environments, the script uses the following inputs:
-
-* Dev environment:
-  - Distro name and version. Together, these comprise the base container image.
-  - `poetry.lock` and `pyproject.toml`. Together, these comprise the build
-    context.
-* End-user environment:
-  - Distro name and version. Together, these comprise the base container image.
-  - `.deb` / `.rpm` Dangerzone package, as found under `deb_dist/` or `dist/`
-    respectively.
-
-Any change in these inputs busts the cache for the corresponding image. In
-theory, this means that the Dangerzone environment for each commit can be built
-reproducibly. In practice, there are some issues that we haven't covered yet:
-
-1. The output images are:
-   * Dev: `dangerzone.rocks/build/{distro_name}:{distro_version}`
-   * End-user: `dangerzone.rocks/{distro_name}:{distro_version}`
-
-   These images do not contain the commit/version of the Dangerzone source they
-   got created from, so each one overrides the other.
-2. The end-user environment expects a `.deb.` / `.rpm` tagged with the version
-   of Dangerzone, but it doesn't insist being built from the current Dangerzone
-   commit. This means that stale packages may be installed in the end-user
-   environment.
-3. The base images may be different in various environments, depending on when
-   they where pulled.
-
-## State
-
-The main goal behind these Dangerzone environments is to make them immutable,
-so that they do not require to be stored somewhere, but can be recreated from
-their images. Any change to these environments should therefore be reflected to
-their Dockerfile.
-
-To enforce immutability, we delete the containers every time we run a command or
-an interactive shell exits. This means that these environments are suitable only
-for running Dangerzone commands, and not doing actual development in them
-(install an editor, configure bash prompts, etc.)
-
-The only point where we allow mutability is the directory where Podman stores
-the images and stopped containers, which may be useful for developers. If this
-proves to be an issue, we will reconsider.

-# gVisor integration
-
-> [!NOTE]
-> **Update on 2025-01-13:** There is no longer a copied container image under
-> `/home/dangerzone/dangerzone-image/rootfs`. We now reuse the same container
-> image both for the inner and outer container. See
-> [#1048](https://github.com/freedomofpress/dangerzone/issues/1048).
-
-Dangerzone has relied on the container runtime available in each supported
-operating system (Docker Desktop on Windows / macOS, Podman on Linux) to isolate
-the host from the sanitization process. The problem with this type of isolation
-is that it exposes a rather large attack surface; the Linux kernel.
-
-[gVisor](https://gvisor.dev/) is an application kernel, that emulates a
-substantial portion of the Linux Kernel API in Go. What's more interesting to
-Dangerzone is that it also offers an OCI runtime (`runsc`) that enables
-containers to transparently run this application kernel.
-
-As of writing this, Dangerzone uses two containers to sanitize a document:
-* The first container reads a document from stdin, converts each page to pixels,
-  and writes them to stdout.
-* The second container reads the pixels from a mounted volume (the host has
-  taken care of this), and saves the final PDF to another mounted volume.
-
-Our threat model considers the computation and output of the first container
-as **untrusted**, and the computation and output of the second container as
-trusted. For this reason, and because we are about to remove the need for the
-second container, our integration plan will focus on the first container.
-
-## Design overview
-
-Our integration goals are to:
-* Make gVisor available to all of our supported platforms.
-* Do not ask from users to run any commands on their system to do so.
-
-Because gVisor does not support Windows and macOS systems out of the box,
-Dangerzone will be responsible for "shipping" gVisor to those users. It will do
-so using nested containers:
-* The **outer** container is the Docker/Podman container that Dangerzone uses
-  already. This container acts as our **portability** layer. It's main purpose
-  is to bundle all the necessary configuration files and program to run gVisor
-  in all of our platforms.
-* The **inner** container is the gVisor container, created with `runsc`. This
-  container acts as our **isolation layer**. It is responsible for running the
-  Python code that rasterizes a document, in a way that will be fully isolated
-  from the host.
-
-### Building the container image
-
-This nested container approach directly affects the container image as well,
-which will also have two layers:
-* The **outer** container image will contain just Python3 and `runsc`, the
-  latter downloaded from the official gVisor website. It will also contain an
-  entrypoint that will launch `runsc`. Finally, it will contain the **inner**
-  container image (see below) as filesystem clone under
-  `/dangerzone-image/rootfs`.
-* The **inner** container image is practically the original Dangerzone image, as
-  we've always built it, which contains the necessary tooling to rasterize a
-  document.
-
-### Spawning the container
-
-Spawning the container now becomes a multi-stage process:
-
-The `Container` isolation provider spawns the container as before, with the
-following changes:
-
-* It adds the `SYS_CHROOT` Linux capability, which was previously dropped, to
-  the **outer** container.  This capability is necessary to run `runsc`
-  rootless, and is not inherited by the **inner** container.
-* It removes the `--userns keep-id` argument, which mapped the user outside the
-  container to the same UID (normally `1000`) within the container. This was
-  originally required when we were mounting host directories within the
-  container, but this no longer applies to the gVisor integration. By removing
-  this flag, the host user maps to the root user within the container (UID `0`).
-  - In distributions that offer Podman version 4 or greater, we use the
-    `--userns nomap` flag. This flag greatly minimizes the attack surface,
-    since the host user is not mapped within the container at all.
-* We use our custom seccomp policy across container engines, since some do not
-  allow the `ptrace` syscall (see
-  [#846](https://github.com/freedomofpress/dangerzone/issues/846)).
-* It labels the **outer** container with the `container_engine_t` SELinux label.
-  This label is reserved for running a container engine within a container, and
-  is necessary in environments where SELinux is enabled in enforcing mode (see
-  [#880](https://github.com/freedomofpress/dangerzone/issues/880)).
-
-Then, the following happens when Podman/Docker spawns the container:
-
-1. _(outer container)_ The entrypoint code finds from `sys.argv` the command
-   that Dangerzone passed to the `docker run` / `podman run` invocation.
-   Typically, this command is:
-
-   ```
-   /usr/bin/python3 -m dangerzone.conversion.doc_to_pixels
-   ```
-
-2. _(outer container)_ The entrypoint code then creates an OCI config for
-   `runsc` with the following properties:
-   * Use UID/GID 1000 in the **inner** container image.
-   * Run the command we detected on step 1.
-   * Drop all Linux capabilities.
-   * Limit the number of open files to 4096.
-   * Use the `/dangerzone-image/rootfs` directory as the root path for the
-     **inner** container.
-   * Mount a gVisor view of the `procfs` hierarchy under `/proc` , and then
-     mount `tmpfs` in the `/dev`, `/sys` and `/tmp` mount points. This way, no
-     host-specific info may leak to the **inner** container.
-     - Mount `tmpfs` on some more mountpoints where we want write access.
-3. _(outer container)_ If `RUNSC_DEBUG` has been specified, add some debug
-   arguments to `runsc` (applies to development environments only).
-4. _(outer container)_ If `RUNSC_FLAGS` has been specified, pass some
-   user-specified flags to `runsc` (applies to development environments only).
-5. _(outer container)_ Spawn `runsc` as a Python subprocess, and wait for it to
-   complete.
-6. _(inner container)_ Read the document from stdin and write pixels to stdout.
-   - In practice, nothing changes here, as far as the document conversion is
-     concerned. The Python process transparently uses the emulated Linux Kernel
-     API that gVisor provides.
-7. _(outer container)_ Exit the container with the same exit code as the inner
-   container.
-
-## Implementation details
-
-### Creating the outer container image
-
-In order to achieve the above, we add one more build stage in our Dockerfile
-(see [multi-stage builds](https://docs.docker.com/build/building/multi-stage/))
-that copies the result of the previous stages under `/dangerzone-image/rootfs`.
-Also, we install `runsc` and Python, and copy our entrypoint to that layer.
-
-Here's how it looks like:
-
-```dockerfile
-# NOTE: The following lines are appended to the end of our original Dockerfile.
-
-# Install some commands required by the entrypoint.
-FROM alpine:latest
-RUN apk --no-cache -U upgrade && \
-    apk --no-cache add \
-    python3 \
-    su-exec
-
-# Add the previous build stage (`dangerzone-image`) as a filesystem clone under
-# the /dangerzone-image/rootfs directory.
-RUN mkdir --mode=0755 -p /dangerzone-image/rootfs
-COPY --from=dangerzone-image / /dangerzone-image/rootfs
-
-# Download and install gVisor, based on the official instructions.
-RUN GVISOR_URL="https://storage.googleapis.com/gvisor/releases/release/latest/$(uname -m)"; \
-    wget "${GVISOR_URL}/runsc" "${GVISOR_URL}/runsc.sha512" && \
-    sha512sum -c runsc.sha512 && \
-    rm -f runsc.sha512 && \
-    chmod 555 runsc /entrypoint.py && \
-    mv runsc /usr/bin/
-
-COPY gvisor_wrapper/entrypoint.py /
-ENTRYPOINT ["/entrypoint.py"]
-```
-

-## Security considerations
-
-* gVisor does not have an official release on Alpine Linux. The developers
-  provide gVisor binaries from a GCS bucket. In order to verify the integrity of
-  these binaries, they also provide a SHA-512 hash of the files.
-  - If we choose to pin the hash, then we essentially pin gVisor, and we may
-    lose security updates.
-
-## Alternatives
-
-gVisor can be integrated with Podman/Docker, but this is the case only on Linux.
-Because we want gVisor on Windows and macOS as well, we decided to not move
-forward with this approach.

-# Reproducible builds
-
-We want to improve the transparency and auditability of our build artifacts, and
-a way to achieve this is via reproducible builds. For a broader understanding of
-what reproducible builds entail, check out https://reproducible-builds.org/.
-
-Our build artifacts consist of:
-* Container images (`amd64` and `arm64` architectures)
-* macOS installers (for Intel and Apple Silicon CPUs)
-* Windows installer
-* Fedora packages (for regular Fedora distros and Qubes)
-* Debian packages (for Debian and Ubuntu)
-
-As of writing this, only the following artifacts are reproducible:
-* Container images (see [#1047](https://github.com/freedomofpress/dangerzone/issues/1047))
-
-In the following sections, we'll mention some specifics about enforcing
-reproducibility for each artifact type.
-
-## Container image
-
-### Updating the image
-
-The fact that our image is reproducible also means that it's frozen in time.
-This means that rebuilding the image without updating our Dockerfile will
-**not** receive security updates.
-
-Here are the necessary variables that make up our image in the `Dockerfile.env`
-file:
-* `DEBIAN_IMAGE_DIGEST`: The index digest for the Debian container image
-* `DEBIAN_ARCHIVE_DATE`: The Debian snapshot repo that we want to use
-* `GVISOR_ARCHIVE_DATE`: The gVisor APT repo that we want to use
-* `H2ORESTART_CHECKSUM`: The SHA-256 checksum of the H2ORestart plugin
-* `H2ORESTART_VERSION`: The version of the H2ORestart plugin
-
-If you update these values in `Dockerfile.env`, you must also create a new
-Dockerfile with:
-
-```
-make Dockerfile
-```
-
-Updating `Dockerfile` without bumping `Dockerfile.in` is detected and should
-trigger a CI error.
-
-### Reproducing the image
-
-For a simple way to reproduce a Dangerzone container image, you can checkout the
-commit this image was built from (you can find it from the image tag in its
-`g<commit>` portion), retrieve the date it was built (also included in the image
-tag), and run the following command in any environment:
-
-```
-./dev_scripts/reproduce-image.py \
-    --debian-archive-date <date> \
-    <digest>
-```
-
-where:
-* `<date>` should be given in YYYYMMDD format, e.g, 20250226
-* `<digest>` is the SHA-256 hash of the image for the **current platform**, with
-  or without the `sha256:` prefix.
-
-This command will build a container image from the current Git commit and the
-provided date for the Debian archives. Then, it will compare the digest of the
-manifest against the provided one. This is a simple way to ensure that the
-created image is bit-for-bit reproducible.

-# Update notifications
-
-This design document explains how the notification mechanism for Dangerzone
-updates works, what are its benefits and limitations, and what other
-alternatives we have considered. It has been adapted by discussions on GitHub
-issue [#189](https://github.com/freedomofpress/dangerzone/issues/189), and has
-been updated to reflect the current design.
-
-A user-facing document on how update notifications work can be found in
-https://github.com/freedomofpress/dangerzone/wiki/Updates
-
-## Design overview
-
-This feature introduces a hamburger icon that will be visible across almost all
-of the Dangerzone windows. This will be used to notify the users about updates.
-
-### First run
-
-_We detect it's the first time Dangerzone runs because the
-`settings["updater_last_check"] is None`._
-
-Add the following keys in our `settings.json` file.
-
-* `"updater_check": None`: Whether to check for updates or not. `None` means
-  that the user has not decided yet, and is the default.
-* `"updater_last_check": None`: The last time we checked for updates (in seconds
-  from Unix epoch). None means that we haven't checked yet.
-* `"updater_latest_version": "0.4.2"`: The latest version that the Dangerzone
-  updater has detected. By default it's the current version.
-* `"updater_latest_changelog": ""`: The latest changelog that the Dangerzone
-  updater has detected. By default it's empty.
-* `"updater_errors: 0`: The number of update check errors that we have
-  encountered in a row.
-
-Note:
-
-* If on Linux, make `"updater_check": False`, since we normally have
-  other update channels for these platforms.
-
-### Second run
-
-_We detect it's the second time Dangerzone runs because
-`settings["updater_check"] is not None and settings["updater_last_check"] is
-None`._
-
-Before starting up the main window, show this window:
-
-* Title: Dangerzone Updater
-* Body:
-
-  > Do you want Dangerzone to automatically check for updates?
-  >
-  > If you accept, Dangerzone will check the latest releases page in github.com
-  > on startup. Otherwise it will make no network requests and won't inform you
-  > about new releases.
-  >
-  > If you prefer another way of getting notified about new releases, we suggest adding
-  > to your RSS reader our [Mastodon feed](https://fosstodon.org/@dangerzone.rss). For more information
-  > about updates, check [this webpage](https://github.com/freedomofpress/dangerzone/wiki/Updates).
-
-* Buttons:
-   - Check Automaticaly: Store `settings["updater_check"] = True`
-   - Don't Check: Store `settings["updater_check"] = False`
-
-Note:
-* Users will be able to change their choice from the hamburger menu, which will
-  contain an entry called "Check for updates", that users can check and uncheck.
-
-### Subsequent runs
-
-_We perform the following only if `settings["updater_check"] == True`._
-
-1. Spawn a new thread so that we don't block the main window.
-2. Check if we have cached information about a release (version and changelog).
-   If yes, return those immediately.
-3. Check if the last time we checked for new releases was less than 12 hours
-   ago. In that case, skip this update check so that we don't leak telemetry
-   stats to GitHub.
-4. Hit the GitHub releases API and get the [latest release](https://api.github.com/repos/freedomofpress/dangerzone/releases/latest).
-   Store the current time as the last check time, even if the call fails.
-5. Check if the latest release matches `settings["updater_latest_version"]`. If
-   yes, return an empty update report.
-6. If a new update has been detected, return the version number and the
-   changelog.
-7. Add a green bubble in the notification icon, and a menu entry called "New
-   version available".
-8. Users who click on this entry will see a dialog with more info:
-
-    * Title: "Dangerzone v0.5.0 has been released"
-    * Body:
-
-       > A new Dangerzone version been released. Please visit our [downloads page](https://dangerzone.rocks#downloads) to install this update.
-       >
-       > (Show changelog rendered from Markdown in a collapsible text box)
-    * Buttons:
-       - OK: Return
-
-Notes:
-* Any successful attempt to fetch info from GitHub will result in clearing the
-  `settings["updater_errors"]` key.
-
-### Error handling
-
-_We trigger error handling when the updater thread encounters an error (either
-due to an HTTPS failure or a Python exception) and does not complete
-successfully._
-
-1. Bump the number of errors we've encountered in a row
-   (`settings["updater_errors"] += 1`)
-2. Return an update report with the error we've encountered.
-3. Update the hamburger menu with a red notification bubble, and add a menu
-   entry called "Update error".
-4. If a user clicks on this menu entry, show a dialog window:
-    * Title: "Update check error"
-    * Body:
-
-       > Something went wrong while checking for Dangerzone updates:
-       >
-       > You are strongly advised to visit our [downloads page](https://dangerzone.rocks#downloads) and check for new updates manually, or consult [this page](https://github.com/freedomofpress/dangerzone/wiki/Updates) for common causes of errors . Alternatively, you can uncheck "Check for updates", if you are in an air-gapped environment and have another way of learning about updates.
-       >
-       > (Show the latest error message in a scrollable, copyable text box)
-
-   * Buttons:
-      - Close: Return
-
-## Key Benefits
-
-1. The above approach future-proofs Dangerzone against API changes or bugs in
-   the update check process, by asking users to manually visit
-   https://dangerzone.rocks.
-2. If we want to draw the attention of users to immediately install a release,
-   we can do so in the release body, which we will show in a pop-up window.
-3. If we are aware of issues that prevent updates, we can add them in the wiki
-   page that we show in the error popup. Wiki pages are not versioned, so we can
-   add useful info even after a release.
-
-## Security Considerations
-
-Because this approach does not download binaries / auto-updates, it **does not
-add any more security issues** than the existing, manual way of installing
-updates. These issues have to do with a compromised/malicous GitHub service, and
-are the following:
-
-1. GitHub pages can alter the contents of our main site
-   (https://dangerzone.rocks)
-2. GitHub releases can serve an older, vulnerable version of Dangerzone, instead
-   of a new update.
-3. GitHub releases can serve a malicious binary (requires a joint operation from
-   a malicious CA as well, for extra legitimacy).
-4. GitHub releases can silently drop updates.
-5. GitHub releases can know which users download Dangerzone updates.
-6. Network attackers can know that a user has Dangerzone installed (because we ask the user to visit https://dangerzone.rocks)
-
-A good update framework would probably defend against 1,2,3. This is not to say
-that our users are currently unprotected, since 1-4 can be detected by the
-general public and the developers (unless GitHub specifically targets an
-individual, but that's another story).
-
-## Usability Considerations
-
-1. We do not have an update story for users that only use the Dangerzone CLI. A
-   good assumption is that they are on Linux, so they auto-update.
-
-## Alternatives
-
-We researched a bit on this subject and found out that there are update
-frameworks that do this job for us. While working on this issue, we decided that
-integrating with one framework will certainly take a bit of work, especially
-given that we target both Windows and MacOS systems. In the meantime though, we
-didn't want to have releases out without including at least a notification
-channel, since staying behind on updates has a huge negative impact on the
-users' safety.
-
-The update frameworks that we learned about are:
-
-## Sparkle Project
-
-[Sparkle project](https://sparkle-project.org) seems to be the de-facto update
-framework in MacOS. Integrators in practice need to care about two things:
-creating a proper `Appcast.xml` file on the server-side, and calling the Sparkle
-code from the client-side. These are covered in the project's
-[documentation](https://sparkle-project.org/documentation/).
-
-The client-side part is not very straight-forward, since Sparkle is written in
-Objective-C. Thankfully, there are others who have ventured into this before:
-https://fman.io/blog/codesigning-and-automatic-updates-for-pyqt-apps/
-
-The server-side part is also not very straight-forward. For integrators that use
-GitHub releases (like us), this issue may be of help:
-https://github.com/sparkle-project/Sparkle/issues/648
-
-The Windows platform is not covered by Sparkle itself, but there are other
-projects, such as [WinSparkle](https://winsparkle.org/), that follow a similar
-approach. I see that there's a [Python library (`pywinsparkle`)](https://pypi.org/project/pywinsparkle/)
-for interacting with WinSparkle, so this may alleviate some pains.
-
-Note that the Sparkle project is not a silver bullet. Development missteps can
-happen, and users can be left without updates. Here's an [example issue](https://github.com/sparkle-project/Sparkle/issues/345) that showcases this.
-
-## The Update Framework
-
-[The Update Framework](https://theupdateframework.io/) is a graduated CNCF
-project hosted by Linux Foundation. It's based on the
-[Thandy](https://chromium.googlesource.com/chromium/src.git/+/master/docs/updater/protocol_3_1.md)
-updater for Tor. It's [not widely adopted](https://github.com/sparkle-project/Sparkle/issues/345), but some of its
-adopters are high-profile, and it has passed security audits.
-
-It's more of a [specification](https://github.com/sparkle-project/Sparkle/issues/345)
-and less of a software project, although a well-maintained
-[reference implementation](https://github.com/sparkle-project/Sparkle/issues/345)
-in Python exists. Also, a [Python project (`tufup`)](https://doc.qt.io/qtinstallerframework/ifw-updates.html)
-that builds upon this implementation makes it even easier to generate the
-required keys and files.
-
-Regardless of whether we use it, knowing about the [threat vectors](https://theupdateframework.io/security/) that it's protecting against is very important.
-
-## Other Projects
-
-* Qt has some updater framework as well: https://doc.qt.io/qtinstallerframework/ifw-updates.html
-* Google Chrome has it's own updater framework: https://chromium.googlesource.com/chromium/src.git/+/master/docs/updater/protocol_3_1.md
-* Keepass rolls out its own way to update: https://github.com/keepassxreboot/keepassxc/blob/develop/src/updatecheck/UpdateChecker.cpp
-* [PyUpdater](https://github.com/Digital-Sapphire/PyUpdater) was another popular updater project for Python, but is now archived.

-# Podman Desktop support
-
-Starting with Dangerzone 0.9.0, it is possible to use Podman Desktop on
-Windows and macOS. The support for this container runtime is currently only
-experimental. If you try it out and encounter issues, please reach to us, we'll
-be glad to help.
-
-With [Podman Desktop](https://podman-desktop.io/) installed on your machine,
-here are the required steps to change the dangerzone container runtime.
-
-You will be required to open a terminal and follow these steps:
-
-## On macOS
-
-You will need to configure podman to access the shared Dangerzone resources:
-
-```bash
-podman machine stop
-podman machine rm
-cat > ~/.config/containers/containers.conf <<EOF
-[machine]
-volumes = ["/Users:/Users", "/private:/private", "/var/folders:/var/folders", "/Applications/Dangerzone.app:/Applications/Dangerzone.app"]
-EOF
-podman machine init
-podman machine set --rootful=false  
-podman machine start
-```
-Then, set the container runtime to podman using this command:
-
-```bash
-/Applications/Dangerzone.app/Contents/MacOS/dangerzone-cli --set-container-runtime podman
-```
-
-In order to get back to the default behaviour (Docker Desktop on macOS), pass
-the `default` value instead:
-
-```bash
-/Applications/Dangerzone.app/Contents/MacOS/dangerzone-cli --set-container-runtime default
-```
-
-## On Windows
-
-To set the container runtime to podman, use this command:
-
-```bash
-'C:\Program Files\Dangerzone\dangerzone-cli.exe' --set-container-runtime podman
-```
-
-To revert back to the default behavior, pass the `default` value:
-
-```bash
-'C:\Program Files\Dangerzone\dangerzone-cli.exe' --set-container-runtime podman
-```
